We deal with a ( 1 , 1 ) -tensor field α on the tangent bundle T M preserving vertical vectors and such that J α = - α J is a ( 1 , 1 ) -tensor field on M , where J is the canonical almost tangent structure on T M . A connection Γ α on T M is constructed by α . It is shown that if α is a V B -almost complex structure on T M without torsion then Γ α is a unique linear symmetric connection such that α ( Γ α ) = Γ α and ∇ Γ α ( J α ) = 0 .

In this paper we consider a method by which a skew-symmetric tensor field of type (1,2) in M n can be extended to the tensor bundle T q 0 ( M n ) ( q > 0 ) on the The results obtained are to some extend similar to results previously established for cotangent bundles T 1 0 ( M n ) . However, there are various important differences and it appears that the problem of lifting tensor fields of type (1,2) to the tensor bundle T q 0 ( M n ) ( q > 1 ) on the presents difficulties which are not encountered in the...
